The jerkbait water-temperature chart

Surface temperature decides how long a jerkbait should sit still. These are the bands we fish by. They're a starting point, not a law: clarity, the last front and the fish themselves get a vote.

About this number

Data: U.S. Geological Survey, National Water Information System, site 09429490 (COLORADO RIVER ABOVE IMPERIAL DAM, AZ-CA). USGS labels recent readings provisional, so they can be revised. Your browser pulls the latest reading straight from USGS when this page loads.

It's one sensor at one spot. Backwaters, eddies and tributary mouths run warmer or colder than the main channel, and the water a few feet down can be a different story from the surface. Treat it as the starting read, then trust your own electronics.
